Hello everyone, 

We’ve had annoying issues to say the least with our Sonos system (beam + 2x One SL) since the November update. 
 

We had no issues up until then, everything worked perfectly, be it when we played music, watched tv or used any streaming service. But since November, it’s all gone haywire and it’s driving me crazy. I keep trying to change the settings but nothing works, no setting stays the same for everything like it used to. Before that darn update, I only touched *once* the settings, and that’s when we installed the system over 2 years ago. It worked oh so well up until November. 
 

Dialogues are muffled, but then all the other sounds are too loud. I have to turn up the volume to hear what’s being said and then end up deafening the whole house when all the other sounds come on. It’s like the sound is on stereo. And then, sounds aren’t on time with the image. It was NEVER like this. 
 

We contacted the customer service and had no helpful answer, we were told the last update didn’t affect sound. Has anyone had a similar issue lately ?

And if that doesn’t help, I would suggest you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, their lawyers get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I’d suggest forcing a check for updates on speakers and app, to be sure everything is up to date. Then check for your router updates too. Then power off all Sonos devices and the router. Wait a few minutes before restarting the router. Wait until it’s fully restarted and the wifi is up and running before restarting your Sonos devices. For home theatre configs, be sure the soundbar is running before powering up the surrounds and Sub. 
 

See how it sounds after that kind of reset.
